CHURN.

Specication of Letters Patent.

Patented Mar. 11, 1913.

To all whom t may concern Be it known that I, ANDREW J. MALONE, a citizen of the United States, residing at Edmond, in the county of Oklahoma and State of Oklahoma, have invented certain new and useful Improvements in Ohurns; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to improvements in churns.

One object of the invention is to provide an improved construction and arrangementof operating mechanism whereby the dasher of the churn may be rapidly and easily operated either by hand or power.

Another object is to provide an improved means for adjusting the stroke of the dasher andreadily operated means for detachably connecting the dasher rod to the dasher operating mechanism.

Another and essential feature of the invention is in the particular construction of the dasher as will appear from the detail description to follow, whereby, the cream is more thoroughly agitated and converted into butter.

A further object is to provide means whereby the churn operating mechanism may be readily moved from place to place.

With these and other objects in view, the invention consists of certain novel features of construction, and the combination and arrangement of parts as will be more fully described and claimed.

In the accompanying drawings; Figure 1 v is a side view of one side of my improved churn operating mechanism; Fig. 2 is a similar view of the opposite side; Fig. 3 is an end view of one end of the mechanism; Fig. 4 is a vertical cross section through the operating mechanism and rthe -adjustablev My improved churn operating mechanism compris-es a supporting frame consisting of a flat bas-e 1 to which are secured the lower ends of upwardly projecting side frames 2 which are preferably formed of angle iron bars and are suitably connected together and spaced apart by cross bars 3.

Revolubly mounted in suitable ball bearings in the upper bars of the frames 2 is a main drive shaft 4 which may be provided with mea-ns for attaching a suitable motor thereto or with a crank handle 5 as herein shown. On the shaft 4 is fiXedly mounted a sprocket gear 6 which is connected by a sprocket chain 7 with a. sprocket gear 8 on a dasher operating shaft 9, revolubly mounted in ball bearings arranged in the upper bars of the side frames 2 near the opposite ends thereof from the shaft 4 as shown.

On one end of the shaft 9 is iiXedly mount` ed a dasher operating disk 10 having therein a radially disposed slot 11 by means of which a dasheroperating mechanism hereinafter described is adjustably connected thereto. On the shaft 9 is i'iXedly mounted a. balance or fly wheel 12 having on one side a grooved belt pulley 13, the purpose of which will be hereinafter described.

My improved dasher operating mechanism comprises a guide frame 14 secured to one of the side frames 2 over the shaft 9 and dasher operating disk 10. The frame 14 has in its outer side a vertically disposed guide slot 15 and in its upper end a guide passage 16. Slidably engaged with the slot 15 in the frame 14 is a dasher supporting and guiding block 17 on the inner side of which is arranged a guide plate or bar 18 the upper end of which projects through and slidably engages the guide passage 16 in the upper end of the frame 14 as shown. On the inner side of the block 17 is arranged a stud 19 to which is connected the outer end of a pitman rod 20 the inner end of which is pivotally connected to a wrist pin 2l having its inner end reduced and threaded and adjustably engaged with the slot 11 in the disk 10 and secured by a clamping nut 22 screwed onto said threaded end of the wrist pin as shown. By thus adjustably connecting the wrist pin 21 to the disk 10 it will be seen that the stroke of the pitman rod and the guide block 17 connected thereto may be regulated and the stroke of the dasher thereby controlled.

The sliding engagement of the block 17 with the slot 15 in the frame and of the guide bar 1S with the passage 16 will hold the block 17 in vertical alinement when reciprocated by the disk 10 and pitman rod 20.

Bolted or otherwise rigidly secured to the outer side of the block 17 is a dasher clamping mechanism comprising a vertically disposed plate 23 having` its ends bent outwardly at right angles and provided with V-shaped notches to form seats 21 for the dasher rod 25 of the churn; The pglate 23 has formed thereon or secured thereto a horizontally disposed curved arm 2G the end of which is disposed adjacent to the outer side of the dasher rod. In the outer end of the arm 26 is a threaded passage with which is engaged a dasher clamping screw 27 which, when screwed inwardly against the outer side of the dasher rod firmly clamps the same into engagement with the seats 24 in the ends of the plate 23 and thereby firmly secures the dasher rod in position to be actuated by the operating mechanism hereinbefore described. By thus adjustably securing the dasher rod the same may be supported at any desired position above the bottom of the churn with which the same is engaged.

The dasher rod 25 has arranged on its lower end an improved dasher comprising a plate 2S which is preferably of hexagonal shape and to the hexagonal edges of the plate are hingedly connected a series of paddles 29 and 30. The paddles 29 are hinged to the plate 28 to swing upwardly when the dasher is forced downwardly in the churn, while the paddles 30 are hinged to swing downwardly when the dasher is pulled up in the churn, or in other words, the series of paddles 29 and 30 swing in opposite directions as the churn is reciprocated. The paddles 29 are provided with suitable stops which hold the same in horizontal position while the dasher is being pulled upwardly in the churn, while the paddles 30 are provided with suitable stops which hold the same in a horizontal position when the dasher is being forced downwardly in the churn. By this construction and arrangement of the paddles it will be seen that three of the same are in working position on the down stroke of the dasher, while the other three are in operative position on the upper stroke of the dasher, said series of paddles being arranged alternately around the plate 28 as shown.

It has been found in practice that a dasher constructed as herein shown and described will mo-re thoroughly agitate the cream and more quickly produce the butter than dashers of the ordinary construction.

In connection with the dasher `operating mechanism 1 Preferably provide@ rotary,

fan 31 whereby flies or other insects are eifeotually kept away from the mouth or upper end of the churn. The fan comprises aA shaft 32 which is revolubly mounted in suitable bearings on one end of the side frames 2 and has fixed thereon a pulley 33 which is connected by a belt 34k with the pulley 13 on the side of the fly wheel 12 whereby said fan shaft is driven by the dasher operating shaft 9. The blades 34 of the fan are secured to the end of the shaft 32 and are disposed in a position adjacent to the upper end of the churn so that the air or draft created by the fan will drive flies and other insects away from the churn while in operation. n

In order to facilitate the moving of the operating mechanism from place to place, I preferably provide carrying wheels 35 which are revolubly mounted on the cranked outer ends of a supporting shaft 3G journaled in suitable bearings on one end of the base 1 as shown. To the shaft is secured a shifting lever 37 having on its upper end a spring catch arm 38 adapted to be sprung into engagement with a catch pin 39 secured in one of the side frames 2 as shown. By thus constructing and arranging t-he shaft 36 and lever 37 it will be seen that the shaft may be rocked by the lever to swing the wheels 35 downwardly or upwardly into or out of engagement with the floor and that when said wheels are swung downwardly and t-he lever 37 secured in the manner described that this end of the supporting base and frame will be elevated above the floor and supported on said wheels, thus permitting the device to be readily moved from place to place.

It will be understood that any suitable form of churn body or receptacle 40 may be employed in connection `with my improved dasher operating mechanism and that it is simply necessary to place the churn body on the base 1 below the dasher rod and dasher and to adjust the dasher rod to bring the dasher at the desired elevation above the bottom of the churn body whereupon the churning operation may be carried on.

From the foregoing description taken in connection with the accompanying draw ings, the construction and operation of the bars suitably connected and supported and properly spaced, a bearngsecured to said frame, a drive shaft mounted in said bearing, a sprocket wheel fixed to the shaft, a

dasher operating shaft a sprocket gear on the latter, a sprocket chain connecting said sprocket wheels, a guide bar slidably mounted in the frame, a disk secured to the shaft and having a slot formed therein, a pitman rod revolubly secured to the guide bar and having its opposite end adjustably and movably secured to the slotted portion of the disk and means attached to the guide bar for detachably clamping a dasher rod in a vertical position in respect to said bar.

2. In a churn supporting frame a guide bar slidably mounted in the same means for reciprocating said bar, a clamp secured to the latter for attachably and detachably securing a dasher rod, the opposite ends of said plate being projected outwardly and provided with V-shaped notches, a curved projecting arm forming a rigid part of the plate and centrally disposed between the notched end of the plate, the end of the curved arm terminating substantially on av line with the center of the plate whereby the dasher rod may be readily removed from the clamp thus formed, and a binding screw carried by the end of the arm and adapted to be brought in contact with a dasher rod properly disposed between the V-shaped notched ends of the plate.

In testimony whereof I have hereunto set my hand in presence of two subscribing witnesses.
